When I get to the command that invokes the CreateAzureFailoverCluster powershell script, I check the state of the failover cluster. In Failover Cluster Manager, it is shown as "the cluster network name is not online"

Each of the 3 servers in the cluster has access to the DC via ping. All of the preceding setup steps execute correctly. The servers are all on the 10.10.2.x/24 IP range except the DC, which is on 10.10.0.0/16 (with IP of 10.10.0.4)

All of the settings have been validated by prior execution of the tutorial on a different Azure subscription to create a failover cluster that works fine.

Cluster validation reveals this warning:

The "Cluster Group" does not contain an Cluster IP Address resource. This is a required resource for the group. It may be difficult to manage the cluster with this resource missing

Did you setup a fixed IP address in the cluster, using the cluster manager? there's a bug, DHCP will assign the cluster the IP address of one of the sql server isntances. I just assigned a high enough number (x.x.x.171, I think), and the problem went away.
